Dallas’ double came after he had scored just two goals in his previous 39 Championship appearances this season, 33 of which he had started.

Whelan was particularly impressed the combination play by Cook and Dallas for the opener.

“It was lovely play by Lewis Cook to get the ball down the right and then Stuart Dallas turns, gets it out of his feet and it’s a lovely shot from outside the box and into the bottom corner,” he told BBC Radio Leeds.

“We’ve seen a Leeds United team do things with purpose, whether that’s closing down or moving the ball quickly.”
